In April 1952, Naval Construction Battalion Unit 1804 assisted in the construction and maintenance received by MAG-33 at K-3. Here at the port of Pohang, a detachment from the 1st Combat Service Group controlled the movement of fuels, oils, lubricants, and ordnance to wing dumps. Amphibian tractors (LVTs) of Company B, 1st Amphibian Tractor Battalion, provided most of the transportation required for these supplies excepting ordnance. Assistance in the form of amphibious trucks (DUKWs) was furnished by a platoon from the 1st Amphibian Truck Company. When required, Marines of these two companies manhandled the supplies. Logistical support for the Marine wing was governed by the same general procedures that applied to the division; 1st MAW supply requirements beyond its augmented capability became the responsibility of Eighth Army (2d LogCom) which furnished items common to both Marine and Army units. If this EUSAK agency did not stock the requisitioned item, it provided a substitute. Responsibility for resupply of aviation items rested with the U.S. Navy. Commander, Naval Forces, Far East (ComNavFE) replaced unserviceable aviation technical equipment such as aircraft parts and special maintenance tools. Commander, Service Force, Pacific (ComServPac) replenished aviation ordnance. Responsibility for supplying items peculiar to the Marine Corps rested with CG, FMFPac. The repair and maintenance of 1st MAW equipment posed far less of a problem than the construction and upkeep of airfields. Major repair work on aircraft was satisfactorily performed in Japan by the wing support squadron at Itami, and by the U.S. Navy Fleet Air Service Squadron 11 (FASRon-11), located at the Naval Air Station, Atsugi. The establishment in Japan of the wing heavy maintenance facility depended, in part, upon its proximity to the wing flying squadrons. Other considerations were the availability to the wing commander of adequate air transport for continuous resupply of both routine and emergency items and reliable communications between the users and the maintenance unit. Because these conditions favoring removal of the heavy maintenance facility from the immediate combat area existed throughout Korean hostilities, it was possible for the maintenance units to operate successfully in Japan away from the combat zone.
